About the book: 2022 / In the book “Scouts of the outer planets: the journey of the “Pioneers” and “Voyagers” from Earth to Neptune and Beyond" Igor Lisov sets out in fascinating detail the history of the preparation, planning, financing, launches and flights of the Pioneers and Voyagers - spacecraft whose mission was to explore the planets of the outer solar system. These expeditions provided incredibly valuable information about Jupiter, Saturn, Uranus and Neptune - celestial bodies about which mankind's knowledge had previously been very superficial. The two Voyagers are still in flight to this day: gradually losing power, they stop sending signals and move further and further from Earth, beyond the solar system. These ships are never destined to return, but on board the Voyagers carry messages from earthlings to extraterrestrial civilizations - in case such a meeting ever takes place.
